I first solved a mip problem and write the solution to sol file or mst file. Then, I delete a few constraints and want to use the previous solution as a mip start.
1. Which is the right way to restore the previous solution? mst file or sol file?
2. Since the mst file only has the solution of the integer variables. I want to use mip start for a continuous solution as well, how can I do that?
3. I know if I delete some constraints, the solution will be cleared. In what condition, the start attribute will be cleared?
